or my "hands with palms facing down" test.... no matter how hard I try it just can't get open hands, palms down.
I guess the vast majority of images have the palms the other way, that this biases the output. It's like how we misinterpret images to generate optical illusions, because we're expecting valid 3D structures (Escher's staircases, say).
